Thunder Bay International Airport, or "YQT" (its international aeronautical designation)
is a major airport for northern Ontario. The terminal is southwest of downtown, just past
Thunder Bay Expressway and Arthur (see Map). It is accessible from the Transportation-Canada
Highway, and is only minutes for the city's south downtown.
The airport is serviced by the major Canadian airlines,and is a major jumping off point for smaller airlines' flights into Ontario's northern mining country, and for float planes to take off into lake country.
